Wondering if thiers a disadvantage to this ?

 

don't know about solid, but I have used the FD corners and springs with great results

 

I belive the rubber seals allow for better low RPM sealing....

 

Ok thnx.

 

whats the difference in the fd and fc corner seals?

 

There's no difference in the corner seals.

The springs on the other hand... one's a peice of wire (non-fd), the other is a copper cutout. Get the FD corner seal springs...

 

Corner seals are the same for FC and FD.
Corner seal springs are a BIG difference. The FC ones are like a paper clip thickness whereas the FD ones are much more rigid and heavy duty and yes you can use them for FC engines. I've seen the solid corner seals but never used them. I think they were recently introduced by Atkins Rotary since it wasn't available when I did the rebuild.

 

They were used in earlier rotary engines... far from new.

 

Rubber inserts dissapear after a while. Solid corner seals are stronger at the bottom. The fc corner seals break in half due to the thinner bottom part. I rebuilt my engine and did not even bother to use rubber inserts. It's all up to you guys...

 

Then again your engine is in a drag-spacific racecar.

 

This is on my daily driven 87 turbo carb. N/A, not the race car.

 

no rubber inserts = weight reduction!!!

 

uhhhh... metal weighs more than rubber, doc...

 

hurley now has some cool corner seals, don't know about how good they are though. Ask around!

 

I've seen the hurley corner seals, and made a point about them.

What they did was move the rubber insert peice up, as some people supposedly were breaking the thinnest part of the corner seals. The problem that comes with this is, there's less of the corner seal holding the apex seal perpendicularly.

 

Thnx for the answere (5 months later)

 

Where do you get corner seals with no inserts?
